What happens when Doug starts listening in the middle of a song? Or if a part of the song starts looping?
In the game we’ve dealt with both of these things, very early on. Coming in on the middle of a song acts just like starting from the beginning — either the power “analyzes” the song for future use (if it is not familiar) or the particular effects activate (if it is). Of course, in the latter case it lasts for less time.
